The hole 11 serves so that a locking insertion member 30 and an elastic fastening member 40 are assembled to the cover 10. When they are assembled the locking insertion member 30 is positioned outside of the cover 10 and the elastic fastening member 40 is positioned inside of the cover 10.

The locking insertion member 30 includes a body 31 covered its top with a reinforcement element 35 for its strength, and a locking insertion protrusion 32 formed on the body 31 for the insertion to the hole 11. The locking insertion protrusion 32 forms a tapered surface 34 toward the cover 10 to have a increased diameter gradually and forms a locking groove 33. The top of the tapered surface 34 is its diameter larger than that of the hole 11.

The elastic fastening member 40 includes a body 41 and a hole 42. The hole 42 enables the locking insertion member 30 to be fastened to the elastic fastening member 40 via the cover 10 since the locking insertion protrusion 32 of the locking insertion member 30 is inserted into the hole 42 after passed through the hole 11 of the cover 10. The body 41 forms a downwardly tapered surface 41 b for preventing the separation of the locking insertion member 30.

The elastic fastening member 40 is formed its end with the bending portion for keeping a gap from the cover 10. The gap serves to prevent a damage of the cover 10. Furthermore, the elastic fastening member 40 forms an embossing 43 for preventing an excessive contact to the cover 10. These structures of the elastic fastening member 40 serve to prevent a damage of the cover 10. The embossing 43 is formed in the manner of a press working and is formed its opposition side with a concave portion 43 a.

Meanwhile, as shown in FIGS. 13 and 14, it is possible that the protrusion 32 of the locking insertion member 30 is formed to have a pin shape and the elastic fastening member 40 is formed for inserting the protrusion 32. In this case, after the protrusion 32 is inserted into the fastening elastic member 40, the lower part of the protrusion 32 is its shape changed to have an extended diameter when the top of the protrusion 32 is pressed down using a tool. Therefore, the protrusion 32 is not separated from the elastic fastening member 40.

The body 20 forms a hole 21 for assembling a fastening member 50, a lower member 60, an elastic locking member 70 and an upper member 80.

The fastening member 50 includes a body 51, and a fastening protrusion 52 for securing the lower member 60 via the hole 21. The protrusion 52 is inserted into a hole 62 of the lower member 60, and thereafter its top is pressed down to have a larger diameter than that of the hole 62. The portion pressed down of the protrusion 52 is tightly contacted to the inner bottom surface of the lower member 60 so that the fastening member 50 and the lower member 60 are tightly fastened each other.

The lower member 60 includes a body 61, and a hole 62 for inserting the protrusion 52 of the fastening member 50 passed through the hole 21 of the body 20.

The elastic locking member 70 is made of metal, non-metal or plastic. The elastic locking member 70 includes a circular plate 71 fastened to the inner bottom of the lower member 60. The circular plate 71 forms an elastic insertion portion 72 having a triangle shape for inserting the protrusion 32 of the locking insertion member 30 fastened to the cover 10. The plate 71 also forms a tapered surface 73 having a certain slope upwardly except the elastic insertion portion 72, and a hole 74 for the locking and unlocking of the locking groove 33 of the locking insertion member 30 fastened to the cover 10. The hole 74 opens in the central portion of the elastic insertion portion 72.

The elastic locking member 70 can forms a plurality of tapered surfaces 73 so that the protrusion 32 can be softly separated from the elastic locking member 70 by the elastic force so that the damage such as its breakdown can be prevented.

The upper member 80 includes a body 81 for covering the lower member 60, a hole 82 for inserting the protrusion 32 of the locking insertion member 30 fastened to the cover 10 and for inserting the protrusion 52 of the fastening member 50 fastened to the body 20, and a tapered surface 83 having a certain slope upwardly from the hole 82 for easily inserting the protrusion 31 to the hole 82.

Next, the assembly steps of the locking device capable of securing the bag having the above constructions will now be described.

As shown in FIGS. 1 to 3, the protrusion 32 of the locking insertion member 30 is inserted into the hole 11 of the cover 10 and is inserted into the hole 42 by the elastic force of the elastic fastening member 40 without difficulty. Then the protrusion 32 can be prevented the separation from the elastic fastening member 40 because the tapered surface 34 is its top diameter larger than that of the hole 42. Therefore, the locking insertion member 30 and the elastic fastening member 40 are assembled to the cover 10.

As shown in FIG. 4, under a state that the elastic locking member 70 is put on the inside bottom of the lower member 60, the lower member 60 is covered with the upper member 80. The protrusion 52 is inserted into the hole 21, then the top of the protrusion 52 is passed through the hole 62. Under this state, the top of the protrusion 52 is pressed down so that the top diameter of the protrusion 52 became larger than that of the hole 62, and accordingly the fastening member 50 and the lower member 60 are combined each other. As a result of that, the fastening member 50, the lower member 60, the elastic locking member 70 and the upper member 80 are assembled to the body 20.

Next, the locking operation of the device will now be described.

The protrusion 32 is inserted into the hole 74 through the hole 82 so that the locking groove 33 of the protrusion 32 is locked by the hole 74.

Since the tapered portion 73 keeps a certain slope upwardly from the hole 74 under the state that the elastic locking member 70 is tightly contacted to the inside bottom of the lower member 60, the separation of the protrusion 32 can be prevented. That is, to be separated the protrusion 32 from the hole 74, the tapered portion 73 should be gone upwardly according to the movement of the protrusion 32. However, the movement like that is not easily possible due to the slope degree of the tapered portion 73. Therefore, the locking state can be kept.

The unlocking operation is adversely performed of the operation of the locking.

A second embodiment of the present invention will now be described. The locking device capable of securing the bag according to the second embodiment of the present invention, as shown in FIGS. 5 to 7, changes the structure of the locking insertion member 30.

When the protrusion 32 of the locking insertion member 30 is inserted into the hole 42 of the elastic fastening member 40 via the hole 11, the fastening protrusion 38 is also passed through the hole 42 via the hole 11. Therefore, since the diameter of the protrusion 38 is larger than that of the hole 42, the locking insertion member 30 is fastened to the elastic fastening member 40 via the cover 10.

A third embodiment of the present invention will now be described. The locking device capable of securing the bag according to the third embodiment of the present invention, as shown in FIGS. 9 and 10, changes the structure of the locking insertion member 30.

The locking insertion member 30 forms a groove 37 on the lower surface of the protrusion 32 for being inserted with a C-shaped ring 39. The ring 39 has a lager diameter than that of the protrusion 32. Therefore, when the ring 39 is inserted into the groove 37, the surface surrounded with the ring 39 is its diameter larger than that of the surface of the protrusion 32.

Therefore, the locking insertion member 30 is prevented the separation from the cover 10 and the elastic fastening member 40.

Under a state that the protrusion 32 of the locking insertion member 30 is inserted into the hole 11 of the cover 10, the ring 39 is combined to the groove 37 so that the locking insertion member 30 is prevented the separation from the elastic fastening plate 40.

A fourth embodiment of the present invention will now be described.

The locking device capable of securing the bag according to the fourth embodiment of the present invention, as shown in FIGS. 11 and 12, changes the structures of the elastic fastening member 40 and the upper member 80.

The elastic fastening member 40 forms dissected protrusions 41 a on the hole 42. The protrusions 41 a are bent toward the outer surface of the protrusion 32 of the locking insertion member 30.

The upper member 80 forms a tapered surface 83 that is upwardly slope from the hole 82. The tapered surface 83 serves that the protrusion 32 is guided and easily inserted into the hole 82.
